MonophysitismMonophysitism (məˈnɒfɪsaɪˌtɪzəm or məˈnɒfɪsɪˌtɪzəm) or monophysism (məˈnɒfɪzɪzəm) (from Greek μόνος , "solitary" and φύσις , "nature") is a Christology that states that the person of the incarnated Word (that is, in Jesus Christ) there was only one nature—the divine". The First Council of Nicaea (325) declared that Christ was divine (homoousios, consubstantial, of one being or essence, with the Father) and human (was incarnate and became man).
Chalcedonian ChristianityChalcedonian Christianity is a term referring to the branches of Christianity that accept and uphold theological resolutions of the Council of Chalcedon, the fourth ecumenical council, held in 451. Chalcedonian Christianity accepts the Christological Definition of Chalcedon, a Christian doctrine concerning the union of two natures (divine and human) in one hypostasis of Jesus Christ, who is thus acknowledged as a single person (prosopon).
Quinisext CouncilThe Quinisext Council (Concilium Quinisextum; Penthékti Sýnodos), i.e., the Fifth-Sixth Council, often called the Council in Trullo, Trullan Council, or the Penthekte Synod, was a church council held in 692 at Constantinople under Justinian II. It is known as the "Council in Trullo" because, like the Sixth Ecumenical Council, it was held in a domed hall in the Imperial Palace (τρούλος [] meaning a cup or dome). Both the Fifth and the Sixth Ecumenical Councils had omitted to draw up disciplinary canons, and as this council was intended to complete both in this respect, it took the name of Quinisext.
Catechetical School of AntiochThe Catechetical School of Antioch was one of the two major centers of the study of biblical exegesis and theology during Late Antiquity; the other was the Catechetical School of Alexandria. This group was known by this name because the advocates of this tradition were based in the city of Antioch, one of the major cities of the ancient Roman Empire.
